Woodcut of the morse from Olaus Magnus' Historiae de Gentibus Septentrionalibus (1558 edition).

Featured on PDR in the essay Decoding the Morse: The History of 16th-Century Narcoleptic Walruses

Amongst the assorted curiosities described in Olaus Magnus' 1555 tome on Nordic life was the morse — a hirsute, fearsome walrus-like beast, that was said to snooze upon cliffs while hanging by its teeth. Natalie Lawrence explores the career of this chimerical wonder, shaped by both scholarly images of a fabulous North and the grisly corporeality of the trade in walrus skins, teeth, and bone.
